Abstract
An inductor structure () formed in an integrated circuit () is disclosed, and includes a first isolation layer () and a first core plate () disposed over or within the first isolation layer (). The first core plate () includes a plurality of electrically coupled conductive traces composed of a conductive ferromagnetic material layer. A second isolation layer () overlies the first isolation layer and an inductor coil () composed of a conductive material layer () is formed within the second isolation layer (). Another core plate may be formed over the coil. The one or more core plates increase an inductance (L) of the inductor coil ().
